So, I was over at a guy who I occasionally buy tools and scrap iron from, when I saw this really weird air compressor sitting in the yard, I asked him about it, and he told me it was available... I really didn't need ANOTHER project, but it was so weird, I threw $20 at him, and it came home with me...

I've since done some digging, (I.E. found someone who knew better) and it turns out, it's made out of an Oxygen tank from a WWII Flying Fortress! Either a B-17 or a B-27. So, I figured I'd share it!

Supposedly, they were rated for 400+ PSI originally. It's either stainless, or aluminum, I can't really tell for sure which, I won't know until I do some cleaning up on it, but it's non-magnetic. So internal rust through shouldn't be an issue...

I might do that, won't be hard... A new motor, pulley, and V belt and it should just work. I don't know about painting it, though... It might be cooler if I removed the paint entirely from the tank, or maybe painted the tank and left the ribbing bare, would be very retro :3
